Use each of the terms below only once to complete the passage. abiotic factors climax community ecological succession ecosystems fire lava flow pioneer species primary succession secondary succession (11) ___________________________ are constantly changing. Both (12) ___________________________ and biotic factors change in every ecosystem. One type of ecosystem change, called (13) ___________________________ , results in one community replacing another over time. This process might begin on bare rock, such as a(n) (14) ___________________________ . The process begins when (15) __________________________ begin living on the rock. This process is called (16) __________________________ . The mature community that eventually forms is called the (17) _________________________ . Sometimes that community is destroyed by a(n) (18) _________________________ . A new community will replace the destroyed one through the process of (19) _________________________ . In your textbook, read about primary succession. Number the pictures below in the order in which they occur, showing the changes that take place during primary succession. 20. ____________________ 22. ____________________ 21. ____________________ 23. ___________________ In your textbook, read about ecological succession. Respond to each statement. 24. Name the material that is present for secondary succession that is not present for primary succession. 25. Cite two reasons why secondary succession is faster than primary succession. 26. Recall the name for the mature community that develops in secondary succession.
